Abstract
Aim: To evaluate the amount of apically extruded debris produced byWaveOne Gold (WOG) and ProTaper Next (PTN) after using mechanical or manual glide path techniques. Methodology: Forty freshly extracted human permanent mandibular first molars were collected and randomly assigned into one of the two main groups (I&II) (n=20 for each group) according to the instrumentation techniques used using either the WOG or the PTN, then each group was randomly subdivided into two subgroups (A&B) (n=10 for each subgroup) according to the type of instrument used to create the glide path using either the PathFiles (PF) or the K-Files (KF). During instrumentation, the apically extruded debris (AED) was collected into pre-weighed Eppendorf tubes. Then tubes were incubated at 70? C for 5 days. The net weight of the apically extruded debris was calculated in gram by subtracting the pre-weight of the empty tubes from the post-weight. The data were statistically analyzed. Results: Using the WOG/KF was statistically significantly associated with the highest amount of the AED followed by the PTN/KF and WOG/PF with no significant difference between them while the PTN/PF was statistically significantly associated with lowest amount of the AED. Conclusions: Although all systems caused apical extrusion of debris, using the multi-file continuous rotary system with mechanical glide path files could be considered as a promising and reliable approach to prepare the root canal with less amount of debris extruded apically.
